Unions are historically liberal democratic correct? Which I assume makes them PC...and if so very dissapointing for a company like Harley.
It also depends on what sort of Union, and what part of the country they are in. Police and Fire Unions will vote for Republicans a lot more than the Private Sector Unions. Certain Union vocations are more prone to vote Republican than others.
Unions mostly don't care about all the Democrat social issues, they mainly support the party for what they see as their own economic self interest.
These "blue collar" Democrats are more likely to support Trump, especially if they see him as beating back foreign competition and bringing jobs back to America, or other things they see as in their own best interests.
The worst Unions are the public sector Unions that are not Police or Fire. Government Employees unions invariably vote Democrat.
